3. Augmented reality that helps anyone conquer public speaking.

Public speaking could get a whole lot easier with Winning Friends, augmented-reality software that would give you real-time updates about your audience and tips to make your presentation the best it can be.

"Whether you're talking to a single person or a whole stadium, Winning Friends is your guide to mastering persuasion," an IFTF report states.

With the app, you'd know exactly when to smile more or project your voice so that you appear confident and authoritative.

5. Blood kits to give people with the rarest blood type a way to stay safe and make money.

There's a blood type only 43 people in the world are known to have, an ultra-rare "Golden blood" that is a true universal donor. It's known as Rh-null.

The problem is that those 43 people can only accept Rh-null blood.

Frauenfelder says home donation kits could allow people with Golden blood to sell it at a high cost — upward of $2,400 a liter. They could save the profits for when they need to buy more of it in the event of an injury.

7. Microbial Mood Rings that give people unprecedented access to their health.

The Microbial Mood Ring would contain a perfect replica of the wearer's microbiome. When you encounter an environment that might negatively affect that bacteria, the ring would change colors, prompting you to leave or perhaps just wash your hands.

"I think that would be incredibly useful as a guide to lead you to things are going to be good for you," Frauenfelder says.

8. Reputation Statements that list any good deeds you do.

If we want to gauge someone's worth, we shouldn't go by their bank account, Frauenfelder says. Instead, we should develop a Reputation Statement— an itemized list of each person's monthly social acts, similar to a utility bill.

A nobler form of currency would incentivize people to act in a way that benefits their community, rather than themselves, Frauenfelder says.

"It's proof you've done something good to make this money, and it's not like you made a killing in the stock market."

9. An Indulgence Navigator to provide real-time updates that help you avoid cravings.

10. An augmented reality app that makes exercise a transparent and measurable facet of daily life.

The EZ Lift would encourage people to take the stairs instead of the elevator or escalator.

Each person would start the day with a certain number of "lift" credits; as they exhaust them, an augmented-reality display would let everyone know they're running low. People can earn credits by taking the stairs.

The idea would be to nudge people toward exercise by making public health truly public.
